java - Spring - Hikari CP failing for DB2

问题描述

I am trying to use Hikari connection pooling for my spring based app using xml based bean configuration. Below is my Hikari config bean and I am using the Db2 as my database. 

<bean id="HikariConfig_UId_Primary" class="com.zaxxer.hikari.HikariConfig">
    <property name="poolName" value="uidPrimaryCP" />
    <property name="connectionTestQuery" value="select 1 from sysibm.systables fetch first row only with UR" />
    <property name="dataSourceClassName" value="${Jdbc_DataSourceClassName}" />
    <property name="maximumPoolSize" value="${Jdbc_MaxPoolSize}"/>
    <property name="idleTimeout" value="${Jdbc_IdleTimeOut}" />
    <property name="maxLifetime" value="${Jdbc_MaxLifeTime}" />
    <property name="connectionTimeout" value="${Jdbc_ConnTimeOut}" />

    <property name="dataSourceProperties">
        <props>
            <prop key="url">${Jdbc_UID_Primary}</prop>
            <prop key="user">${Jdbc_UserId}</prop>
            <prop key="password">${Jdbc_Password}</prop>
        </props>
    </property>
    </bean>

<bean id="UID_Primary_DataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
    <constructor-arg ref="HikariConfig_UId_Primary" />
    </bean>

It failing to register the bean, saying the database url property - url does not exists on target class com.ibm.db2.jcc.DB2SimpleDataSource. below is the complete stack trace..

I've connected to Hikari using spring boot but not with xml configuration. See my post here

I think, adding up below property should fix error.

<property name="jdbcUrl" value="" />
<property name="username" value="" />
<property name="password" value="" />
